Tissue paper Pulping Process

Tissue paper is soft, feathery, lightweight, highly absorbent, tear resistant, disposable and relatively strong paper products. The tissue paper name originates from the French word “tissue”, which meaning cloth. Because of the tissue paper is as soft as cloth. It has become an important part in our daily life. Uses of this type of paper are increasing rapidly in worldwide. Overall, a person who lives in a developing country uses some kilograms of tissue paper per year. The people of North American use highest amount of tissue paper; per person about 25 kg per year.As there are two kinds of raw materials: wood pulp and waste paper, Leizhan engineers design and choose two types of pulping machines for customer, and then combine the pulp after pulping.Tissue paper Pulping ProcessWood Pulp Pulping Process:The commercial wood pulp is conveyed into D type hydrapulper for pulping, and then use the pulp pump to convey it into double disc refiner for improving the beating degree and produce high quality fine pulp. After pulp refining, the pulp will be conveyed into tissue paper machine for paper making.Waste Paper Pulping Process:Waste paper is conveyed into high consistency hydrapulper for separating waste paper. Then the pulp will be conveyed into high density cleaner for removing heavy impurities in paper pulp. Besides, the pulp will be conveyed into screening equipment fiber separator, vibrating screen, and pressure screen for pulp screening. Furthermore, the pulp will be conveyed into inclined screw thickner for pulp washing and thickening. Then the waste paper pulp will be conveyed into double disc refiner and combined with wood pulp for paper making.
